500.14 EXTERNAL PAGING
An amplifier for external paging can be connected to
the 616 FLEX Key telephone system. Any tele-
phone in the system can access this paging equip-
ment by using a dial code. There is one External
Paging Zone (without amplifier) provided in the 616
FLEX system.
The output impedance of the paging zone is 600
Ohms. The low level voice signal output is specified
at 5 milliwatts. Dry contact control is provided to
switch on the external amplifier equipment or to
momentarily remove background music, if externally
supplied to the paging device. All connections are
made on the J-l punchdown connector. The voice
output from the key telephone system is provided on
the EPVT and EPVR pair. The “make” contacts are
identified as pair EPCTL. The paging port can be
connected to a two way paging system:
500.15 LOUD BELL CONTROL/CO LINE CON-
TROL
The STARPLUS 616 FLEX system provides relay
contact closure to activate external signaling equip-
ment during incoming CO line ringing. The station
or CO line that is to signal is selected by program-
ming. Refer to System Configuration, Sec. 630.4.
There is one (1) control contact which can be as-
signed to any station or CO line. Locate the control
contact on the terminals of the connecting block.
Two wires are connected to these terminals and
routed to customer provided signaling equipment.
Refer to Figure 500.5.
500.16 EMERGENCY TRANSFER
In the event of a commercial AC power interruption,
the first 3 CO/PBX lines will automatically transfer to
single line telephones (if installed) for emergency
communications. These SLTs should be equipment
with ringers. They can be DTMF type instruments
or rotary dial. Connection is made on the modular
connector located directly on the right side of the
KSU. Refer to Figure 500.4
500.17 HEADSET INSTALLATION
The STARPLUS 616 FLEX Key telephone has been
designed to operate with industry standard modular
headset adapters and operator headsets. To modify
a key telephone to use an external headset:
A. Plug the headset adapter cord into the vacant
headset jack on the key telephone base.
B. Plug the telephone handset cord into the head-
set adapter box where indicated by the headset
manufacturer’s instructions.
C. Turn to the programming section of this manual.
Enable the headset option for that particular
station.
Speakerphone operation is automatically disabled
and such features as On-Hook Dialing and Hands-
free speakerphone become inoperable. However,
incoming page/voice announcements, tone ringing
and background music will still be heard over the key
telephone speaker when the station has activated
the headset mode.
